Knock, knock, knock
Knock, knock, knock
It's chilling.
A dagger flies and pierces my chest.
But don't worry.
Because I'm already fucked.
"Ah."
Like a scene from a horror movie, I kept my head fixed and slowly shifted my gaze to look at the monitor—
There, proudly, a screen filled with a feast of flesh-colored skin was displayed.
Now, let me predict the future.
Kang Seo-ah screams and runs away.
Kang Ji-eun and Kang Yu-na, who came running after hearing the scream, look at me with eyes full of contempt.
I get disowned and kicked out of the house.
As my life flashed before my eyes for a moment, I squeezed my eyes shut and waited silently for number 1 to happen, but.
"Th-th-that..."
"...?"
Kang Seo-ah didn't scream, nor did she run away.
She was just gripping the doorknob tightly.
She was just stuttering as if she were a broken speaker.
The one difference from a speaker was that her face and ears were turning red in real-time.
Soon after, Kang Seo-ah's gaze fell from the monitor, passed over my face once—
"..."
"..."
And reached my pants, which were unnaturally bulging from having been pulled up in a hurry.
Since I had nothing to say, I quietly waited for my fate, and Kang Seo-ah spoke up without being able to take her eyes off my crotch.
"U-um..."
"..."
"Do, do you have... a cha... charger?"
...
A charger?
Kang Seo-ah bringing up a charger in this situation.
That must mean she's implicitly agreeing to pretend she didn't see anything, just like with Kang Yu-na.
My brain, which had momentarily stopped functioning, started spinning rapidly.
"...Ah, a charger! I do! Wait a second... H-here."
The command issued by my brain, having quickly assessed the situation, was 'Hurry and give her the charger.'
The result.

"...Ugh, ah..."
Thinking I should pull out the charger and hand it to her quickly, I got too close.
In the momentarily closed distance, I could smell Kang Seo-ah's shampoo.
She reached out to take the charger but stopped, standing still with her head slightly bowed.
Her face, seen up close, was already dyed bright red up to her ears, and her pupils were shaking left and right.
"Seo, Seo-ah...?"
When I called out cautiously, Kang Seo-ah jumped in surprise and took a step back.
Because of that, the charger cord slipped from her hand and fell to the floor.
"N-no... th, that..."
She couldn't continue her sentence properly.
Her gaze lingered on the front of my pants again for a moment, then quickly fell to the floor.
Her hands, having stopped trying to pick up the charger, were clenched into fists.
"I'll... take it later."
She muttered in a voice that sounded like she could barely breathe now.
Then, without saying anything else, she turned around and walked toward the door with long strides.
Bang!
The sound of the door slamming shut echoed through the room.
After Kang Seo-ah left, I heard her footsteps quickly fading away in the hallway.
I stood there blankly, staring at the closed door.
Her shampoo scent still lingered on the tip of my nose, and Kang Seo-ah's flustered breathing remained in my ears.
Thump thump thump thump—
"Hwaaa..."
My heart was beating like crazy.
Not only my face, but my ears and neck were burning so hot that they felt hot just by touching them with my hand.
I definitely saw it.
When I entered Kang Si-woo's room, Kang Si-woo's strangely awkward posture and expression.
And on the monitor I looked at after shifting my gaze—
A scene of a woman spreading her vulva toward the camera was displayed.
And when I lowered my gaze, even the sight of Kang Si-woo's pants bulging unnaturally.
Kang Seo-ah covered her face with both hands.
'I even knocked...'
I did need a charger originally.
But to be honest, it would have been much more comfortable to go to Kang Ji-eun or Kang Yu-na.
I just wanted to see Kang Si-woo's face one more time.
It was an excuse to enter Kang Si-woo's room, and I went there blindly thinking I might be able to smell his scent.
But even after I knocked and heard him tell me to come in.
As soon as I opened the door, the scene from just now unfolded.
"Ugh..."
Kang Seo-ah lay on her back on the bed, spread her legs slightly, and slowly pushed her hand into her pants.

The moment her fingers touched her vulva, which had just started to get wet from the situation earlier, a small moan leaked out.
Jjib-eub♡
"Aheuu...♡"
It was clear that Kang Si-woo had been masturbating.
The pants that were twisted unnaturally as if pulled up in a hurry, the crotch that was bulging as if it would burst through the pants, and that explicit scene on the screen.
As she started to gently rub her clitoris with her finger, she recalled the situation that followed.
When Kang Si-woo suddenly closed the distance while holding the charger.
At that moment, along with Kang Si-woo's scent... a thick, lewd smell brushed past her nose.
"Ha-eung...♡"
That smell was, sometimes when Kang Si-woo went out without ventilating the room.
It was a thicker and lewder smell than the one she had smelled on the bed after sneaking into Kang Si-woo's room.
A smell that made her lower abdomen tremble on its own.
Kang Seo-ah began to add a little imagination to her recollection.
'What if that video wasn't just some woman... but me...?'

The imagination of what it would be like if Kang Si-woo was masturbating while thinking of her, just as she was masturbating while thinking of Kang Si-woo.
'If I hadn't knocked and entered...'
The imagination that if she had just opened the door without knocking, she could have seen Kang Si-woo masturbating in person.
And—

Jjil-geok♡ Jji-geok♡ Jji-geo-eok♡...
"Hut♡ Oppa...♡"
The imagination of Kang Si-woo entering this room right now, seeing her masturbating, and pouncing on her.
Those imaginations began to deepen more and more.
From the hope that maybe Kang Si-woo didn't lock the door because he wanted to be caught by someone, just like her.
To the vague imagination of just going to Kang Si-woo right now and protesting for him to pounce on her.
Thus, Kang Seo-ah's imaginative masturbation continued for a while.
There's something.
Definitely, there's something.
"Unless there's a ghost, it doesn't make sense."
It didn't make sense logically that these things were happening simultaneously all of a sudden in days that had been peaceful and harmonious as usual without any problems.
The flow these days was definitely strange.
I wasn't the type to believe in spiritual beings like ghosts, but it was true that something was strange.
Not only did I get an erection looking at Kang Yu-na, but I almost got an erection while giving Kang Ji-eun a massage.
Even just now, I almost got caught by Kang Seo-ah while masturbating...
"No, I got caught."
Well, these things can happen in life.
But as the person involved, I couldn't help but think that it was happening too suddenly and too often.
Knock knock knock—!
"...! Fuck, you scared me."
Of all times, the knock sounds now.
Because the PTSD from getting caught by Kang Seo-ah earlier came to mind for no reason, I glanced at the monitor.
The monitor was maintaining a black screen as if it had done nothing wrong.
It was natural since I had already turned off the monitor and finished ventilating the room.
"...Come in."
I cleared my throat once and said.
Click—
The door opened, and someone poked their head in.

"...Why is your expression like that?"
It was Kang Yu-na.
As soon as she entered, she saw my face stiffened and asked what was wrong.
Naturally, I couldn't tell her the truth, so I roughly wiped my face and explained.
"Just, I'm having trouble with an assignment."
Since I had a suitable excuse, I was able to make up a natural one.
"Hmm, then are you resting now?"
"...That's true, but why?"
Fortunately, it seemed she passed over it without much suspicion.
"Heh... then, give Noona a massage."
"...Was today the day you asked me to do it later? No, in the first place, I said I'd see—"
"Ah, do it~! Eonni did it for you too. Are you discriminating?"
Kang Yu-na didn't even listen to the answer, opened the door wide, and came into the room.
And then she flopped onto my bed.

I was dumbfounded by her stubbornness.
"No..." "Why? Are you not going to do it?"
I tried to retort, but closed my mouth.
It was because I remembered that Kang Yu-na had passed off yesterday's incident as a joke this morning.
Should I call it a favor? Anyway, thinking about that, it was hard to refuse.
"...Haa."
I let out a long sigh.
Eventually, I sat on the edge of the bed and asked.
"Well... where is uncomfortable?"
Kang Yu-na giggled as if satisfied with my reaction and tossed and turned slightly.
Then she stretched out her legs and tapped her calves with her fingers.
"Here, my legs seem a bit stiff, so hurry up and massage them! Slave Kang Si-woo."
"Ah, yes, yes."
Thinking I should just do it roughly and send her away to rest, I approached the bed while playing along with the roleplay.

"Kyaa~! Kang Si-woo is pouncing on me!"
"..."
She was doing her victim cosplay again with her acting tone.
This time, I didn't play along and looked at her a bit pitifully, so Kang Yu-na turned her body awkwardly.
Soon after, she buried her face in the pillow while lying face down.
"...!!"

In an instant, Kang Yu-na's buttocks were exposed right in front of my eyes.
As her long pajamas rode up to her waist, her soft and elastic buttocks filled my vision.
The thin fabric was pulled taut, showing a certain silhouette—
'...Huh?'
A strangeness crossed my mind for a moment.
'I can't see the panty line, and why...'
But I immediately erased it from my mind and lowered my gaze.
It was because I thought things would get big again like yesterday if I thought about it.
I mean, something else gets big along with the work.
'Let's not think about it.'
I lowered my gaze as much as possible and started singing the national anthem in my head.
'Until the East Sea's waters run dry and Mt. Baekdusan is worn away...'
"Hoo..."
Simultaneously with singing the national anthem, which I don't know how many times I've sung in the last two days, in my head.
I let out a sigh and placed my hands on Kang Yu-na's calves.
